I get the OP. He's trying to find a rational reason to why the pad exists. The main thing companies want you to see is that it's used to create new ways to play stuff. This is true. It's there so that people can come up with new things. But it's also there to hook people.
This is how all products work: A car has this this and this feature. You save money if you do this. This TV show has CGI dragons. This show features strong women etc. Something not of the norm. There's 10 cop shows on TV. They do different things to each other. Allowing them to survive. If each one had 4 people, stereotyped woman, fat doughnut guy and tough black dude. People would stop watching the weaker ones. And your show is dead. People easily accuse things of being unoriginal. It's why movies like Battleship are made. It's something original. But with orginality risk people not liking it (U Pad), or rejecting it (Always online connection). So everything must do something different to justify its existence. In the Wii U's case. The pad doesn't sway enough people to do that. So Nintendo has to focus on other areas now. These things are apart of what determins something's sucess or failure. iPod could of been the loser and Zune winner. If Zune had the things majority of people wanted.
Everything that is trying to be sold to people must make it unquie to its past products and give a reason for the person to look at it, and want to buy it.
